Images captured using the Galaxy S23 and the Galaxy S23+ sometimes showcase permanent blur in some areas, and this issue is especially noticeable when capturing close-up shots. Samsung says that it is due to the primary camera's wider aperture. The company said in its Polish forum (via Android Authority) that engineers are working on solving this issue. A future update could mitigate the problem.
The Galaxy S23's camera blur issue is a result of a wide aperture
Samsung said, “When testing the capabilities of the S23 or S23+ camera, you may have been caught because when you take a close-up photo, the area around the subject looks a bit blurry. That's because the rear wide-angle camera on the S23 and S23 Plus has a bright aperture, which helps when taking photos in the dark. However, it also means that more noticeable selective focus can make the background of your photos look a bit blurry.”
The South Korean firm also offered suggestions to stop this issue from appearing. One of the workarounds involves taking a step back from the subject if it is 30cm away from the camera lens. Another solution is to hold the phone vertically rather than horizontally or obliquely.
Galaxy S9's dual-aperture feature could've been a perfect solution to this problem
Nevertheless, it has taken Samsung a long time to acknowledge the issue. We are unsure if the problem can be solved entirely due to the nature of this issue. This is the exact scenario where a dual-aperture lens could have been convenient. The dual-aperture (F1.5-F2.4) feature was introduced with the Galaxy S9 and was present in the Galaxy S10 but removed since the Galaxy S20.
